Determining the motor torque-speed diagram
If a motor torque-speed diagram is not available, the relevant values can be determined with
sufficient accuracy using the specifications for the maximum torque M
MAX
, the rated torque
M
N
, and the associated speeds n
MAX,MMAX
and n
N
as shown in "Motor torque-speed diagram".
This diagram must be compared with the motor torque-time diagram and the speed-time
diagram (see diagram below). To do so, it is normally sufficient to locate the critical points in
the torque-time diagram at which the maximum speed n
MAX,MMAX
is exceeded at the peak
torque. For these points, the motor torque (in this example: M
1
) can be read from the motor
torque-time diagram and checked to determine whether it lies below the characteristic in the
motor torque-speed diagram.
